The victory was Vettori's first as New Zealand Test captain

Captain Daniel Vettori took four second innings wickets in Dunedin as New Zealand recorded a nine-wicket victory over Bangladesh in the first Test.

The tourists, who were 148-0 overnight, were bowled out for 254 with left-arm spinner Vettori claiming 4-70.

Tamim Iqbal was first go, bowled by Kyle Mills for 84, and opening partner Junaid Siddique followed for 74.

No-one else reached 30 and the Kiwis, left to score just 35 for victory, did so for the loss of Craig Cumming.

Vettori was delighted by his side's improvement after an undistinguished effort in the field on the second day.

"We got caught up in thinking we'd run through them again, so there was a lot of talk [before the start] about what we needed to do.

"It came back to me to set appropriate fields and give the bowlers the right conditions to thrive in...to flip the switch overnight was pleasing," he said afterwards.

The win was Vettori's first as Test skipper and he added: "It's pretty exciting. Your first win as captain is very special."

Bangladesh's hopes suffered a serious setback when both openers departed in successive overs, Tamim's exit being followed by that of Siddique, who edged a ball from Chris Martin to first slip.

Jacob Oram, who was later named Man of the Match, then had Habibul Bashar caught in the gully for 11 and Iain O'Brien hastened Bangladesh's decline by removing skipper Mohammed Ashraful (23) and Aftab Ahmed (0).

The tourists were 206-5 at lunch and only survived 16 overs following the re-start as Vettori won three lbw decisions - including the wicket of Shahriar Nafees, who battled for almost two hours for his 28 - and had Mashrafe Mortaza caught behind.

The final wicket went to pace bowler Martin (2-56), who found the edge of last man Sajidul Islam's bat and keeper Brendon McCullum did the rest.

With so few runs needed, victory was a formality for the home side, although the dismissal of Cumming, who was lbw to Mortaza for four, gave Bangladesh a minor consolation.

Matthew Bell followed his first innings century with an unbeaten 20, but it was Peter Fulton who finished things off in style as he hoisted a ball from Ashraful for a huge six to finish unbeaten on 15.

Having lost the one-day series 3-0, Bangladesh must now find a way to raise their game for the second and final Test in Wellington, but Ashraful and coach Jamie Siddons failed to sound an optimistic note.

"Every Test we have played, we have not batted well in the first innings. That is our biggest problem. Our bowlers bowled quite well. We're going well in some ways, but it is just the first innings that lets us down," said Ashraful.

"They have to find it within themselves to wait for the bad ball and bat some time. I went to bed thinking the worst, and the boys didn't let me down. It's what I've seen all tour - I'm still looking for the answers," Siddons added.
